The carcass of any animal which divides the foot, but is not cloven-hoofed or does not chew the cud, is unclean to you. Everyone who touches it shall be unclean.
And whatever goes on its paws, among all kinds of animals that go on all fours, those are unclean to you. Whoever touches any such carcass shall be unclean until evening.
Also the swine is unclean for you, because it has cloven hooves, yet does not chew the cud; you shall not eat their flesh or touch their dead carcasses.
